BUTTON-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 333,551, dated January5, 1886.

Application filed May 20, 1885.

To all whom it may concern:

Be it known that I, IRA J. SAUNDERS, of Union City, county of Branch,and State of Michigan, have invented an Improvement in Button-Fasteners,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters 011 the drawings representinglike parts.

This invention has for its object the production of a simple andefficient button-fastener by which to hold in place upon boots and shoesthat class of buttons having shank-eyes projecting from their lowersides.

My invention consists of a metallic staplelike fastener bent to form twoprongs, and having a cross bar or crown curved upwardly from a shoulderor shoulders adapted to rest upon the surface of the material to whichthe button isto be attached, the upwardly-curved portion referred tobeing concave at its upper side or top and convex atits under side, thesaid convex portion forming a rest for contact against it of the eye ofthe shank of the button.

In the manufacture of myimproved buttonfastener I prefer to take a thinflat strip of sheet metal and bend the same into the form described, theprongs driven through the material being clinched at the under sidethereof.

Figure 1 in side elevation represents a button-fastener embodying myinvention; Fig. 2, atop view thereof; Fig. 3, a section of Fig. 1 in thedotted line as as. Fig. 4 represents a button held upon a piece ofleather or other material by one of my improved fasteners, and Fig. 5represents a thin flat metal blank fromiwhich my fastener is made.

Referring to the drawings, a, Fig. 5, represents the blank for thefastener, the ends of the blank being beveled, as shown, to enable thesame to more readily enter the mate- Serial No. 166,083. (No model.)

rial b. This blank is bent centrally, and then at a little distance fromits center,to leave the upwardly-curved portion 0, two flat portions, d,and two prongs, e, as represented in Fig. 1, and during its formationthe said fastener has the top of the upwardly-curved portion bent intothe form represented in Figs. 2 and 3, leaving a concave top part and. aconvex lower part. The convexity of the upwardlyourved portion ispreferably substantially the same in curvature as the interior of theeye in the shank f of the button g, the said upwardlycurved portionguiding the button-shank and keeping it in place. The portions d,whichrest upon the surface of the material, determine the distance that theprongs e of the fastener may enter the material.

The button will be applied to the fastener before the prongs e areforced into the material, and thereafter the ends of the prongs will bebent each to clinch into the material, a shown in Fig. 5.

I claim- The herein-described metallic staple-like fastener, bent toform two prongs, and having a cross bar or crown curved upwardly from ashoulder or shoulders, (1, adapted to rest upon the material to whichthe button is to be attached, the upwardly-curved portion being concaveat its upper side or top and convex at its under side, the convexportion forming a rest for contact against it of the eye of the shank ofthe button, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
